Since you deny being him, Andy Christensen, what are your credentials as to a Kinetico warranty and how did you get the one your claim to have?
Are you a Kinetico salesman, or work for Kinetico or are you a Kinetico customer and if a customer, why the handle Water Solutions? That sounds as if you are a water treatment dealer, a "company", are you?
I ask because yesterday in another thread I saw an OP asking you if you are a Kinetico salesman but haven't seen you answer that yet.
Without the pre filter the warranty is 5 years, with the pre filter they extend the warranty to 10 years. And with a few Kinetico control valves that require the pre filter, you void the warranty IF you don't have one, or use the one they installed for you (whether ya wanted one or not).
The same applies to their K5 RO, the warranty says 5 years, and an extra 5 years, that's a total of 10 yrs, IF you also have a Kinetico softener softening the water before the RO.
If you disagree, feel free to prove me wrong by posting a copy of that warranty you say you have.
